The Rikuu earthquake (M = 7. 2) occurred in the Mahiru Mountains in Tohoku district on 31 August 1896. Associated with the earthquake, reverse faults appeared on the surface along the western and the eastern feet of the Mahiru Mountains (Table 1 and Fig. 1), which are known as Senya and Kawafune earthquake faults (YAMASAKI, 1896), respectively. This was the largest on-land surface faulting of reverse fault type among events in historical time in Japan. These surface faults were re-studied.
